# App Builder (SDK) Use this skill whenever the user wants a new holaOS app. Two shapes both ship through the same SDK; pick the one the request needs: 1. **Integration-only module** — Slack, Discord, Notion, Stripe, Linear, anything whose value is "talk to one external service via MCP tools, agent drives, no per-app dashboard". The SDK's default web stub is fine; no `src/client/` directory. 2. **Dashboard app** — vibe-coded content planners, CRMs, kanban-style trackers, podcast-guest managers, anything where the user expects a workspace pane they can look at and click around in. **Has a real shadcn UI** authored under `src/client/` (TanStack Start). The MCP tools are still there — they're how the agent drives the same data the dashboard surfaces. The SDK core (5 primitives below) is identical for both shapes. The dashboard shape adds a `src/client/` directory; that's the only structural delta. All supplemental files named in this skill are bundled beside this `SKILL.md`. Treat those paths as skill-local references that are safe to use in packaged runtimes; do not guess at repo-root paths. ## Tooling discipline for this skill - In the normal build turn, use surfaced workspace file tools for file work: `read` / `search` / `find` / `list` for inspection, `edit` for targeted changes, and `write` for new files or full rewrites. - Do **not** use `bash` heredocs for ordinary app file creation or mutation in the build turn. That includes `package.json`, `app.ts`, `server.ts`,
